IMPROVEMENT IN RAILROAD-FROGS.

Specication forming part of Letters Iatent No. 173,804, dated February 22, lS; application filed January 12, 1876.

To all twhom it may concern Be it known that I, WILLIAM J MonDEN, of Indianapolis, county of Marion and State of Indiana, have invented a new and useful Frog for railroad purposes, of which the following is a description, reference being had to the accompanying drawings: f

l. My invention consists of a metallic plate swaged or formed into a trough, a crosssection of which has the form of a U, and a plan view has the form of a Y. The sides of i `at the wide end is provided with a V-shaped recess, in which are secured the point or V shaped ends of the point-rails, and prevents any lateral motion, and relieves the fastenings of the point or pointed rails thus secured from any side or twisting strain when a train is passing over the frog. Thesides of the trough-plate are made to conform to the curve of the side rails, as well as to the form of the neck and base of .the rails, and are.

firmly secured to the neck of the rails by bolts, rivets, or in any manner that would suggest itself to the mind of an ordinary mechanic. Y U

The side sections of the rails or wings are nicely fitted, and supported by the 'sides of the plate, which are turned up --and fitted nicely to the base and neck, as above described, and -securely fastened in any manner thereto.

VThe sides of the plate thus secured to the side rails or wings give additional strength thereto, and prevent the wings from breaking, .and form a light frog that is strong,

' elastic, and durable, and not liable to become disarranged by continual use.

Figure 1 represents a plan view of a frog embodying my improved trough-plate. 'Fig. 2 is a plan or top view of the trough-plate. Fig. 3 is a side view of Fig. 2. Fig. 4. is a cross-section of the frog taken through `the line h k of Fig. l, showing thel side rails or wings attached to the sides of the troughplate, and the V-shaped point or pointed rails removed from the recess at the bottom of thev plate.

My improved trough-plate is represented by the letters A B C C', each letter representing a different part of the same plate. From the center of the trough to the narrow end a cross-section would show the shape of a U, the extremeeud being wider at the top than near the center, the shape of which is shown at A, in Fig. 4, more fully. rlfhe other or point-supporting end of the trough-plate is made considerably wider, and is provided with a V-shaped recess, into which the V- shaped ends of the rails or point D D are securely fastened in any ordinary manner by means of the holes a b d, audit will be seen that the sides ofthe base of the rails or point D D', which fit into the recess B of the trough-plate, are firmly secured to the bottom, and are further secured by the sides of the V- shaped recess, as shown in Figs. 1, 2, and 4, and the rails or point D D', thus secured, will resist all lateral strain that maybe placed on them by passing trains, and will not become loose or displaced.

The sides. G G' of the trough-plate are made to conform with thecurve of the sidesof the rail sections or wings, asv well as with the form of the neck and base of the rails, as shown in Figs. 1, 2, and more fully in Fig. 4, and` are securely fastened in any :manner to the rails F F', as at g' g'.

The trough-plate i'sformed of any metallic substance, swaged, rolled, or forged into its proper shape, and is made of the proper thickness to withstand all strain that it may be subjected to.

What I claim as my invention, and new, and wish to secure by Letters Patent, is-

A metallic plate, A, formed into a trough, the diverging sides of which are mede to conform to the shape of the sides of thern-l-y In testimony whereof I have hereunto sections F F, and the bottom of the wide signed my name to this speeieation'in the end is formed with a V-sha'ped recess to presence of two subscribing witnesses.

Vreceive and hold secure the ends of the rails r point D D', all constructed and l ari WILLIAM J. MORDEN. ranged to be secured to the rail D Dl F F', Witnesses: and form a railroadirog, substantially as and O. S. LONG, A

for the purposes set forth. THoMAs- A. COLE.
